The RFID is a developing technology that uses radio frequency electromagnetic fields to obtain data for tracking and identifying medical products and goods (RFID Journal, 2012). RFID technologies have two main components: a reader, a tag and the application that makes use of the data the reader reads on the tag (Caldwell-Stone, 2010). The reader can be simple or smart, stationary or mobile and it needs to be connected to a network, especially within an infrastructure that captures data from different sites. In this scenario, the network of readers will be served by a host server, which will manage all data transfer between the readers and a central database. While tags have an antenna attached to a microchip containing a short identification number. …show more content…
Semi-passive tags have greater range than totally passive tags; they have an on-board power source, such as a battery, which is used to run the microchip’s circuitry. However these tags utilize a battery but still operate using backscatter techniques. Finally Active tags have a battery with a life of several years, a larger data capacity and a range of tens of meters. Once the reader reads the tag, the information passes to an “application” that makes use of the information. Examples of the uses of these applications are: keyless entry, self check-in and self check-out, inventory and shelving, counterfeit prevention, tracking of containers, pallets or individual items from manufacturer to

... This paper concentrates on the book Strength Finder 2.0 and within this book they provide you with an assessment test that targets you’re top five strengths. The book gives a description of each strength, and provides a scenario to clarify its meaning. The importance of this assessment will help you distinguish your top strengths and what you can do to apply in the work place. I will share with you my top five strengths, its description, my thoughts, and how I can use those strengths to better my future as a leader. My first strength is achiever, which did not surprise me because I am hard working, and when I set my eyes on a goal I try my hardest until that goal is reached. The achiever theme explains my drive, I have a constant need for achievement. By the end of the day I must always achieve something in order to feel good about myself, and when I do not achieve anything I feel dissatisfied with myself. This strength strongly describes who I am, and no matter what I am doing I feel that this strength applies to any activity that I am doing. I feel that my previous job is a perfect example of my achiever theme. I was a dishwasher/line cook at a restaurant called Sunset Grille and I started working there when I was 21. I started out as dishwasher only making minimum wage, which felt degrading to me, but a job is a job I told myself, and at least I was making money. I did, however strived to make more money; I asked my boss how I could do that...

...Section I: Based on the information provided, we thought it would be best to first look at the provided software and instructions from the assignment. We decided to use the program that was given to us which was Rainbowcrack. The reason behind this being that none of us has had a large amount of experience cracking passwords and there seemed to be a lot of literature on how to use Rainbowcrack online. Dually, to be noted is that we were informed that salting was used on the passwords in order to make cracking them even more difficult. ----(Insert Addition or changes if necessary) Section II: The first thing we did was downloaded and extracted Rainbowcrack on to our respective machines. From there, after reading the documentation that was provided by rainbow crack (readme.txt), we learned that there wasn’t a set install that came provided, instead you click the specific .exe file to use that particular tool. After trial and error we decided that it would be easiest to use the rcrack_gui.exe in order to...

...Administering a wireless network can be very troublesome for anyone involved, but with technology like controller based wireless systems, this task can be made easier to configure. Wireless networks are used to connect computers, devices such as smart phones and tablet wirelessly by relaying data traffic through access points (AP), with little used of wired infrastructure. A few AP can be suitable for a small setting such a two story building, but in large enterprises such as a campus, far more APs would be required. This type of setting would require the wireless technician to configure each AP which can span from more than 100. Luckily Wireless controllers were introduced to help alleviate what would seem like a long tiring process by being the centralised device that helps to manage the deployment of large scale wireless networks and access points. First, wireless controllers provide centralised authentication, load balancing fail over and high security. By eliminating the whole idea of MAC address table and constant update for every single access point on the network, this meant that once an access point has been added to the wireless controller it will be automatically configured to the specifications of the network. Additionally, wireless based controllers offers load balancing by automatically directing traffic away from an access point with high traffic to one with less traffic. The controllers also perform failover capabilities by choosing another neighbouring access...

...1. Yes, sport has a unique ability to transcend ‘race, politics or language group.’ Sport ignites feelings of pride and patriotism in its citizens and it thus forms a strong bond within a country. As seen so obviously in 1994 when the winning of the rugby world cup as well as Nelson Mandela wearing the rugby jersey, brought the entire country closer – this ‘gesture of racial reconciliation which meted heart around the country.’ It unified our diverse nation because in that moment everyone was fore-mostly proudly South African. National sporting events remind the citizens of a country of their common link (to their country) and this feeling of being connected by something bigger than any individual, unifies a nation. 2.1 Image 2: The 1994 Rugby World Cup held in South Africa – when the Springboks won the finals and Nelson Mandela was there to...

...Methods We conducted a systematic review of literature published between 2007, the time at which the last WHO review was conducted, to June 2015 (specific search period: January 1, 2007-June 30, 2015). Our aim was to determine the current state of HIV prevention and care and treatment programmes globally using available literature. Our search included peer-reviewed (Medline, PsycInfo, Sociological Abstracts), internet, and grey literature databases. Additional requests for literature were made to UN agencies (see Tables 1 and 2 for specific search strategy). A total of 430 abstracts were initially identified and entered into an Endnote library. All abstracts in English were reviewed. Studies were excluded if they were: (1) not in English; (2) published prior to 2007; (3) not focused on prison populations; (4) focused primarily on post-release; or (5) not focused on HIV. Papers were also excluded if they did not contain clear sampling methods and/or study details. After initial review, 295 abstracts were deemed not applicable due to duplication, falling outside inclusion criteria, and/or being irrelevant to the review. Full text articles for the remaining 135 abstracts were collected and reviewed. After full text review, 50 articles were retained for data extraction. Results are presented below by thematic areas.

...Question 3 Part A:  A variable power supply converts alternating current that is not regulated, into a constant direct current with the aid of a rectifier. Its main function is to supply a steady voltage to other components such as a device or circuits that are normally operated within specific power supply ranges.  An AC ammeter is a device that has two terminals, has no resistance to flow and is polarized. Usually, an ammeter is connected in series with components of a circuit as it measures the sign and magnitude of AC current passing through the component. In order for this to work the circuit must be open to connect the ammeter.  A CRO (cathode ray oscilloscope) is an instrument that allows you to observe voltages that are always varying as a plot. Its main function is to observe the change of electrical signals over a period of time. This change is displayed as a shape. The waveform being displayed notifies you about characteristics such as frequency, amplitude distortion and rise time.  The lateral search coil is used to measure flux density as well as field strength in the solenoid. This reading is then sent to the oscilloscope so the waveform can be analyzed.  The slinky spring serves as a mean of producing the electromagnetic field due to current flowing through it. PART B:  Connect the variable power supply to the ammeter as well as the slinky spring.  The lateral search coil should be connected to the oscilloscope  Place the slotted base that holds the wooden...

...EXPLORING ENGINEERING ASSIGNMENT 2 NXT SENSORS 1. LEGO LIGHT SENSOR:- Lego Light sensor is one of the sensors that give the robot vision. The Light sensor enables our robot to distinguish between light and dark. It can read the light intensity of colored surfaces. Lego light sensor is also well behaved as such sensors go but the physics of sensing light levels is much more complicated so is the task of interpreting the values returned by light sensors. The light sensor is a passive devices that convert this light energy whether visible or in the infra-red parts of the spectrum into an electrical signal output. Light sensors are more commonly known as “Photoelectric Devices” or “Photo Sensors” because it converts Light energy (photons) into Electricity (electrons). With the help of screwdriver one can adjust the sensitivity of sensor. The light sensor measures how much light is shining on it. It has two modes: “LIGHT” and “DARK”. In “light” mode, the more light shines on the sensor, the higher the signal it sends out. In “dark” mode, it’s just the opposite- the signal increases the darker it gets....

This section also contains information regarding supplementary aids or services that may be needed. The IEP must also contain information regarding, if any, and to what extent Hayden will not participate with his general education peers in the regular classroom. The IEP must also address any accommodations or modifications that may need to be put in place in order to meet Hayden’s individual needs. An example of an accommodation would be that the student will be able to take any classroom, district, or state assessment in a separate, quiet, individual setting. Modifications can include shortening assignments or modifying a classroom assessment. An IEP must also contain information regarding when special education services begin as well as the anticipated frequency, location, and duration of each provided special education service (Turnbull, Turnbull, & Wehmeyer, 2010).

Stakeholders - ATOM, client, young people For the first alternative, “tell the client you're not interested”, ATOM Communication Agency would, obviously, lose a valuable customer. At the same time, however, they would gain a positive recognition for being against underage drinking, an illegal and unethical behaviour. In the future, this would be advantageous in attracting other clients that are more favourable to ATOM, such as those who hope to create anti-drinking campaigns. Young people would be also impacted, since less exposure to negative campaigns can be translated to better health and a more positive community in the long run....
